Patent DE-2809639-A1 (DE)
Title: Mineral fibre prodn. from slag from coal power stations - by mixing in container then transporting liq. state to prodn. appts.
Inventor: IHLEFELD KARL-HELMUT
IPC: C03B37/06
Filed: 1978-03-06
Abstract: Mineral fibres are produced from the slag from coal-fired power stations with melting compartment boilers. The hot, highly liq. slag from >=1 compartments is collected in a storage container which is suitable for mixing, homogenised and only then led off to a fibre producing apparatus. Suitable containers are existing apparatus, e.g. hot iron mixers. Heat lost during the transport from the boilers to the fibre producing apparatus is conducted back to maintain the viscosity required for fibre drawing, centrifuging or blowing. Direct transfer of the liq. slag to the fibre producing plant enables the fibres to be produced with a considerable saving over the previous methods.

Patent DE-2910428-A1 (DE)
Inventor: LEHMANN BERNHARD DIPL ING
IPC: G01N21/45
Filed: 1979-03-14
Abstract: The device for measuring the local density and the time variation thereof is based on the measure of the local refraction index and the variations thereof. The device is particularly used for measuring the local density of compressible mediums when such mediums, for example gas liquid flows, must not be disturbed. The measuring device is applicable to monitoring flows having a speed close to or higher than the sound speed for monitoring the flow of mediums having temperature gradients and it is also applicable to the flow acoustic field. To this effect, the problem to be solved is to provide a device which is readily transportable and easy to manipulate, with which it is possible to measure, by means of the measurement of the corresponding refraction index, the local density of the medium at the measurement location or within the measurement volume and to follow the evolution thereof in the time. To solve this problem, two laser beams (1, 1') coherent between each other are directed so as to intersect within the measurement volume (2) so as to cause interference fringes (3) spaced between each other by a distance (a) to appear at this location. By means of powerful optical means (5) sufficiently remote from the measuring volume (2), an intermediary optical image of the interference fringes (3') is generated and, by means of a micro-lens (6), a considerably enlarged image of a transversal cross-section of this measuring volume is projected in a recording region in the form of a system of parallel interference fringes (3''). At this location, intensity sensitive detectors, for example opto-electronic detectors (8, 8', 8'', 8'''), are arranged in a predetermined configuration. By zero-adjusting the differential signal provided by the detectors (8, and 8'), the particular extreme value of the intensity of the interference fringes (3''') appearing between them is fixed in the space and such value is used as a reference point for the enlargement of the fringe system when the interval (a'') between the fringes varies. At the recording detectors (8'' and 8''') a differentiel electric signal appears corresponding to the spacing of the fringes. This differential signal which is proportional to the spacing (a) of the fringes and, subsequently, inversely proportional to the refraction index, therefore to the density of the medium contained within the measuring volume (2), is converted into a measuring signal (U(t)) by means of an electronic circuit (9').

Title: Signal multiplying amplifier system - has two operational amplifiers of very wide band type operating in parallel and with common signal input and output
Inventor: ZIMMER MANFRED DIPL ING
IPC: H03M1/00
Filed: 1979-05-16
Abstract: The amplifier system is intended for rapid, highly precise analog-digital conversion. It comprises operational amplifiers with a Schottky diode bridge in their feedback branch. Two operational amplifiers (OP1, OP2) of very wide band type are used, having a shared signal input (UE) and a shared signal output (UA). The first amplifier is of non-inverting mode, the second one being inverting at the same rate. In the output and feedback branch of both operational amplifiers are incorporated Schottky diode bridges (B1, B2). A rapid comparator (K) is connected to the shared signal input, the comparator output being fed to a bridge current drive circuit (BT), controlling the Schottky diode bridges. In this manner these bridges operate as an ON-OFF switch with external control for each output signal of the operational amplifiers.

IPC: B60H1/00
Filed: 1979-09-13
Abstract: The heating system has a water/air heat exchanger connected into the engine water cooling loop. A hot-air fan is driven by an electric motor.

Title: Water control circuit for public convenience - provides warm water for rinsing only when requested by user, using logic network, sensor and pushbutton operated by user
Inventor: WERTENAUER HELMUT
IPC: G05D23/13
Filed: 1979-10-29
Abstract: The circuit selectively allows two water currents of differing temp. to be used for rinsing. A logic network (101) responds to the output of a sensor (102) e.g. a reflection sensor responsive to visible light or IR light, indicating the presence of the user and to a signal from a manual push-button or contactless sensor control (103). The logic network provides two output signals (K,W) for the magnetic valves regulating the cold and warm water currents. The output signal (K) for the cold water current has priority and the trailing flank of the sensor signal resets the logic network (101) so that this is the signal supplied. Pref. the logic network (101) has a differentiation stage (109,111) for each input signal coupled to the resetting and setting inputs (R,S) of a flip-flop (110). Respective outputs of the latter are coupled to two AND gates (108,112) also receiving the sensor signal and providing the two output signals (K,W).
